Philippe has been involved with the Tizen project since 2012 when he became the co-maintainer on some of the distributions domain’s in the Common profile. He now works for the Samsung Open Source Group where he actively supports community contributions by helping others who have an interest in free software and open hardware. In particular, he is actively involved in the Tizen and IoTivity communities.

There are several options to build IoTivity for ARM targets or any non x86 hardware, but first you have to decide which operating system you want to use. In this article, I won’t compare OS or devices; instead, I’ll give a couple of hints that apply to ARTIK 5, 7, and 10 devices (not the ARTIK 0 family, which run TizenRT). These steps can also be applied to other single board computers like the Raspberry PI. Build for Tizen with GBS The first and easiest way to build IoTivity is for Tizen, using GBS. This process was explained in a previous article on this blog: An Introduction to Tizen Development on ARTIK For your knowledge, GBS was inspired by Debian’s git-build-package and uses an ARM toolchain that runs in a chrooted ARM environment using QEMU. Both ARTIK boards and the Raspberry Pi are used as Tizen reference platforms. Build for […]

The Connected Car & Fragmentation Traditional car manufacturers have begun including early iterations of touchscreen technology with access to media and apps that can also provide basic HVAC (Heating, Ventilation and A/C) controls for the vehicle. These features can often be accessed through mobile devices with tailor-made apps from each car maker. However, this has led to OEMs building their own ecosystem silos, similar to the trends observed in the smartphone industry. The lack of an open, standardized framework has resulted in a fragmented market, where experiences from one OEM won’t work with another in any streamlined way; consequently, developers aren’t thinking about how to provide a rich user experience that allows cars and drivers to work in unison; this is a huge missed opportunity. Samsung OSG, OCF, and IoTivity The Open Connectivity Foundation (OCF) is creating a specification and sponsoring the IoTivity open source project to deliver an open and secure connectivity and […]

A curious mind recently asked me to share materials about the OCF SmartHome demo, or perhaps I should call it the “Minimalist Smart Switch” instead. The demo was displayed at the Embedded Linux Conference in Berlin, and featured IoTivity running on an ARTIK10 SoC that connected to a Tizen Gear S2 Smartwatch; both run Tizen OS. You will find more technical details in the following slide deck. IoTivity Tutorial: Prototyping IoT Devices on GNU/Linux from Samsung Open Source Group Install Tizen and IoTivity If you want to run it this demo, you can download the system image and uncompress the archive directly to the SD card using QEMU tools.

Once this is completed, insert the SD card into the ARTIK10 and turn it on; it will boot Tizen and launch the IoTivity server. For more information about this, check out the previous blog posts about booting tizen on ARTIK and […]

This article is a direct follow up of my previous post about booting Tizen on the ARTIK10. Before starting, you should bookmark this wiki page as an entry point for Tizen on ARTIK devices. At the 2015 Tizen Developer Conference, I had the opportunity to present a tutorial about Tizen platform development; it’s still valid today. This article is very similar but is adapted for ARTIK10 and ARTIK5 configuration. For some context, check out to the following slide deck along with the recorded video on how to patch Tizen and build with GBS for x86a as well as this page about Tizen:Common on VMware. tdc2015-strategy-devel-20150916 from Phil C Tools Setup If you’re familiar with Tizen you probably know about Git Build System (GBS): a very convenient tool to build packages. It’s adapted from Debian’s git-build-package to support zypper repos. First, gbs and some other Tizen tools need to be installed […]

The fact that Tizen can be run on ARTIK is not the latest breaking news, considering it was previously demonstrated live at the 2015 Tizen Conference. There, the ARTIK project was also explained as an IoT platform of choice. Since then, ARTIK has become a new Tizen reference device, so here are a couple of hints that will help you test upcoming Tizen release on this hardware. First let me point out that Tizen’s wiki has a special ARTIK category, where you’ll find ongoing documentation efforts, you’ll want to bookmark this page. In this article, I will provide a deeper explanation of how to use the bleeding edge version of Tizen:3.0:Common on ARTIK10, and how to start working on this platform. As explained in my previous Yocto/meta-artik article, I suggest you avoid using the eMMC for development purposes; for this article I will boot the ARTIK from an SDcard. In […]

Samsung ARTIK is described by its developers as an end-to-end, integrated IoT platform that transforms the process of building, launching, and managing IoT products. I first saw one a year ago at the Samsung VIPEvent 2015 in Paris, but now there is an ARTIK10 on my desk and I would like to share some of my experiences of it with you. In this post, I will show how to build a whole GNU/Linux system using Yocto, a project that provides great flexibility in mixing and matching components and customizing an environment to support new hardware or interesting software like IoTivity. If you’re looking for Tizen support, it’s already here (check at bottom of this article), but this post will focus on a generic Linux build. Many of the board’s features I will be covering in this article are briefly introduced in the following video: https://youtu.be/7ZUYF21d1zo?#iotivity-artik-20160505rzr.mp4 There are 3 ARTIK models […]

The Samsung Open Source Group is playing an active role in the promotion and adoption of IoT standards across multiple domains. Samsung understands the importance of openness and collaboration to realize the full potential of IoT. One of the key promises we’ve made, is to be open and collaborative in our approach to delivering products and solutions to our customers. This was a core part of the Samsung strategy, as explained in the following video. Samsung has remain committed to this approach and continued to deliver on the promise, year after year. Based on these principles the Open Connectivity Foundation (OCF), a global consortium of leading companies (~170 and growing) focused on creating a standard for interoperable devices and services was founded in 2014. The OCF approach has three key deliverables: An Open Specification: Open Connectivity Foundation An Open Source Implementation: IoTivity A membership driven certification program: OCF certification Through this approach, OCF has created […]

Samsung has recently intensified its focus on improving the driving experience with the launch of Connect Auto. As a coincidence, I tried to put together different efforts from our group to into an open connected car experiment. Check out this video which shows a DIY Tizen fan that’s controlled from an Automotive Linux system and Tizen TM1 mobile device: It’s All About Interoperability It might look a bit over-engineered with all of the devices in this demonstration, but the purpose is to validate communication between devices on a network (WiFi, BT, BLE) in various contexts. Of course, it’s possible to adapt the DIY fan to use an automatic gate mechanism or something else to interact with the driver, or it could even use cloud services that ensure the necessary level of security. Interoperability is the key word here, I believe we’re headed in the right direction following the recent Open […]

Samsung Electronics realizes that open source software is a key component of many of our products. The Open Source Group was formed in 2013 to help guide the company in effective consumption, collaboration and creation of open source, provide a method to advocate for Samsung in external open source communities, and develop consistent strategy and governance policies for the enterprise.
